The Other Woman

My best friend was dating a guy I was very close with. I had met him and lost touch with him but had known him much longer than I had known her. We started talking again while they were dating and he added me on snapchat. Long story short, I sent him nudes and he started to fall for me while he was with her. She found out and broke up with him and now hates me. All our mutual friends hate me too. He is acting distant and upset but he keeps snapping me but I feel likes it's only to keep our streak as we don't talk anymore. She said she would forgive me if I completely stopped talking to him and blocked him. I told her I did and she thinks we don't talk but we still do. I want to choose her because I'm super close to one of our mutual friends who sided with her and said I could get her back if I fixed things with this girl. I don't know what to do.
